I also recommend some select vids from sketchy sex, hazehim and Fraternity X....mostly they're older stuff...the new ones kinda suck...

I LOVE troopcandy....though they're relatively new and people don't update much of them.

I also like brent corrigans early works..especially the one where he DPs...but sadly that vid is technically illegal as he was a minor at the time of filming and is therefore not allowed to be spread anymore

as for more asian flavors:
i like the studios G@mes, Bravo and eros......you'd just have to pick out ones to your taste. since there are quite a lot of them .
